GAS-CLEANER.

Application filed February 8, 1909,

To all whom it may concern:

Be it known that T, BRUCE WALTER, a citizen of the United States, residing at Pittsburgh, in the State of Pennsylvania, have invented certain new and useful Improvements in Gas-Cleaners, of which the following is a specification.

My invention relates to devices for cleaning gases particularly by contact with water, and its primary Object is to provide a more efiicient cleaner in which the gas is brought into intimate contact with cold water without being required to take up vapor or free moisture, and to prevent the accumulation of dirt on the surface of the water, etc.

I have llustrated the invention in a simple form in the acconpanying drawing, wherein- Figure 1 is a side elcvation of my device; Fig. 2 is a section on the line (2) in Fig. 1; Fig. 3 is an enlarged cross-section of a convenient form of water feeding pipe and Fig. %L is a partial side elevation of the same.

Heretofore gas cleaning devices have been used in which particles of dirt were taken out by forcing the gas into violent -collision with a body of water, but in this case the water soon becomes covered with a Soum and its efficiency has been destroyed. There have also been devices in which running water was used and the gas forced through cascades of water, etc., or sprayed into the body of gas; in such cases the gas necessarily took up large quantities of vapor and free moisture and the whole apparatus was complicated and expensive.

Generally speaking, the main idea ofmy device is to pass the gas over a smooth surface of running water and immediately remove the water out of the way.

Various other advantages will hereinafter appear.

As seen in the drawing, I provide a large casing 5 into which the gas enters at the top by a pipe 6 and escapes at the bottom by pipe 7 This is preferably rectangular and may conveniently be made open from side to side for more eflicient cooling by air circulation, and as shown it is built of joined partitions 8, 9, and 10 connecting the two sides of the casing and made gas-tight, so that they collectively provide a series of inclined passages 11 as shown in Fig. 2. That is, the inner construction is such that the entering Specificatou of Letters Patent.

gas first impinges on inclined plate 9 and thence passes down through the vertical spaces 12 and inpinging again and thence suddenly turning and inclining upwardly over the next inclined partition 9 and so forth. The upper surfaces of the plates forming the inclined passages are covered by a thin smooth sheet of fiowing water, ted in by slotted pipes 13, which may all be conveniently made as branches of a main pipe 14: as shown in Fig. 1. These pipes have small slots lying flush with the upper surface of the plates 9 and project a sheet of water down the incline and into troughs 15. These troughs are inclined and the water fiows out of them into discharge pipes 16 which preferably are independent and all empty into a receiving reservoir 17 some distance below the surface; It will be noted that the troughs 15 and a'll the passages are sealed so that the water cutlet is also a gas seal. For more eflicient cooling I may also employ spray pipes for projecting water on the outside surfaces of the inclined passages, as indicated at 27. I preferably use for the pipes 13 a construction 'such as 'shown in Figs. 3 and 4:, where the conduitis made of a main body 18 having a cylindrical section and an upper neck 19 covered by plate 20. Just under the plate 20 there is a series of elongated slots 21 for egress of the water, and in these slots I provide a series of cleaning fingers 22 supported on bars 23 which are parts of a spider attached to shaft 24:. The spider and the fingers of course slide freely and at the outer end the rod 24 is provided with a handle 25 for operating it, and of course this rod makes a water tight j oint with the end of the pipe 13, by means of packing box 26. By .manipulating the handle 25, the cleaning fingers 22 can be slid back and forth in the slots of the water feeding pipe to keep it open and clean.

It will be seen by this construction that the gas frequently changes direction and passes many times in upwardly slanting passages in int-imate contact with large areas of smoo-th water surface, and that this water surface in the meanwhile is constantly renewed so that it is constantly clean and cool; the dirt being carried away at once. Also as the gas becomes cooler in its downward passage it continually meets with new surfaces of cold water. Moreover, the water, after washing the gas is immediately carried of`f,f so that the gas is never in contact with dirty up'through the' riction of water ing surfaces being inclined and covered by running water, while the. water -outlet troughs also are inclined, it will be noted. that, I entirely avoid any pockets` or places where *dirt can collect in the Washer.

' I claim- 1. A gas cleaner comprising a casing having a continuous .series 'of unobstru cted gas passages placed one above another in zigzag fashion and having inclined surfaces means for ,providing :on said surfaces a conl stantly flowing sheet of Water in contact with the gas and flowing in opposite .c lirec-- tion to the movement of the gas, and means' for carrying of the water from each incli-ned surface independently.

2. A gas cleaner comprising a casing provided with a continuousseries of zg-zag passages 'vertically arranged therein and forming an unobstructed passage *for gas, means supplying a s'heet of water on the' bottom of each assage entirely below 'the gas therein and an outlet carrying ofi' 'the water from each of said incli-ned surfaces immediately and independently, substanclined' -passages and extending -at its lower end .out of the Zone of the fiowing gas and a gas tight passage and 'discharge receptacle for the water on each one of said surfaces substantially as described.

4. In a gas cleaner, the combinat ionwith an inclined plate forming part .of a gas 2 passage, -a water seal outlet from the same, and a supply pipe adapted' to feed a sheet of water on the p'late, 'the said pipe having .anarrow `slit outlet for the water, and means to clean the said outle't without interrupting the ;flow of water. y

'5. A vgas cleaner-comprising a .casing having uno'bstructed gas passages formed 'by inc-lined plates having each an independent means to drain water therefrom said casing being open to admi't free circulation of air z under the surface of 'the gas passage.

In testimony whereof I have hereunto signed 'my name in the presence of the two subscribed w-itnesses. V
